To disable Media Sense, please perform the following steps:

1)     Click on the Start button.

2)     Type cmd in the search bar.

3)     Right click on the cmd.exe and select Run as Administrator.

4)     Run the following commands one by one:

netsh interface ipv6 set global dhcpmediasense=disabled

5)     After finishing the commands above, please run the following commands to check the results:

Please check if the entry “DHCP Media Sense” shows disabled or not. If it is disabled, it means the operations are successful.

However, please also note, the Media Sense depends on the NIC; if the NIC didn’t support the Media Sense, the configurations won’t take effect, either. Therefore, please also check the issue with the technical support of your NIC.
